Definitions

  • the present invention relates to a cable connector. It finds application in professional electronics, in particular for connecting a sheet of wires conformed in any way. In one embodiment, it makes it possible to easily connect the earths of the cable and of the device to which the cable is connected.
  • connection of the ground conductor often poses a problem, especially when it is desired to ensure good continuity of the masses between the connected devices and ensure good protection of the connector itself.
  • the invention relates to a multi-wire cable connector of the type comprising a plug of a first type connected to the wires of one end of the cable, the plug being of the type coming to connect on a plug of a second kind.
  • the socket (2) of the first kind comprises a transfer piece (7, 8, 9) ensuring the shielding at least upstream of said socket of the first kind, and having a mechanical rigidity of so as to mechanically reinforce the connection of the cable (5) to said socket of the first kind (2), in particular when it is inserted into the second socket and a means of connecting the socket of the first kind with the transfer piece to ensure the transmission of mechanical forces by the transfer part during the extraction of the plug of the first kind.
  • the transfer part comprises a part (20) forming a pawl intended to be fitted into a housing of the equipment to be connected (13), and thus ensuring the electrical connection of the cable shield with the ground. machine.
  • the part (20) is made in the form of a comb consisting of teeth (201-208) folded in a U shape to improve its elastic qualities and also comprises two lateral flaps (21a, 21b) intended to guide the assembly. when inserting on the second socket.
  • a clamp (31, 32) presses on either side of the cable (1) and ensures by tightening the electrical contact of the transfer part (7, 8, 9) with the shielding fabric (4 ).
  • the connecting means consists of a U-shaped piece which is removably or not secured to the socket of the first kind, to form a loop in which the teeth (20) of the comb have passed.
  • a flat cable (1) consists of a layer of wires (3) welded laterally in a single plane perpendicular to the plane of the figure.
  • the cable is protected by a flexible plastic sleeve (6).
  • a conductive fabric (4) which surrounds the sheet (3).
  • the two faces of the fabric are referenced 4a and 4b.
  • the end of the ribbon cable (3) is largely free from the cable outlet (1) and the end of each wire is connected to a socket or terminal block (2).
  • the ends of the wires of the sheet are engaged in insulation displacement members known from the prior art.
  • the mechanical connection of the wires can be completed by a fixing member which will be described later in an exemplary embodiment.
  • This configuration is completely classic. It is often supplemented by a clamp (31, 32) which will be described in connection with FIG. 3 and by a removable fixing member from the socket (2) to the chassis (13) of the device to which the cable is connected.
  • this member consists of two screws secured to the clamp and which engage in corresponding threads linked to the chassis of the device, which has the effect of securing mechanically the cable, its connector and the device to which it is electrically connected.
  • the continuity of the masses is often achieved by welding on the shielding fabric (4) a wire which transmits to the connector the shielding mass of the cable.
  • the wire is either directly connected to the chassis of the device (13), or else connected to a pin of the socket (2).
  • the socket (2) is open and therefore can both radiate electromagnetic energy from the circulation of currents in the sheet, as well as pick up coming from the radio frequency interference field. It is therefore necessary to protect the socket (2) against these disturbances, by making the blind connection inside the device through an opening in the chassis (13) of the device.
  • This transfer part comprises a first part ( 14) which is inserted between the shielding fabric (4) and the ply of wires (3) to contribute to the continuity of the shielding of the part of the ply of wires (3) not protected by the shielding (4).
  • the part also comprises a part (7, 8) which partially envelops the bornir (2) so as to also make its shielding.
  • the parts (14, 7, 70, 8, 9) substantially form a ⁇ the lateral branches (14) and (9) of which are in two offset horizontal planes and the central part (7, 70, 8) forms an inverted U.
  • the terminal block (2) is made integral with the horizontal part (9) of the transfer part.
  • the part (9) of the transfer part with an extension (90) which is intended to penetrate inside the device to be connected so to come, through an opening (130) provided for this purpose in the chassis (13) of the device, in electrical contact with a connection member (10).
  • This member in a preferred embodiment, comprises a conductive track (11) engraved on the face opposite a printed circuit board (10).
  • the extension (90) of the transfer piece electrically contacts this conductive zone thus making a connection of the shielding ground of the cable to the ground of the printed circuit on which the signals of the cable are processed.
  • the socket (2) is made mechanically integral by any means with the part (8) or (9) of the transfer part, to avoid the phenomenon of tearing of the cable (3) from the socket (2) during the extraction of it.
  • the shielding fabric is constituted by a sheet of crossed fine electrical wires.
  • the sheet is folded around the flat ribbon of conductors to be shielded. The two edges of the sheet overlap on one of the flat faces of the ribbon. A simple and easy-to-assemble shielding is thus easily obtained.
  • FIGs 2 there is shown a front view (2A) and profile (2B) of a transfer piece in one embodiment.
  • the transfer piece comprises a first part (17) intended to be introduced between the conductors and, in a first embodiment, the sheath, or in a second embodiment, the collet, as is will see in connection with Figure 3.
  • the second part (8 or 18) allows the push of the first socket by bringing the axis of mechanical push or traction on the axis of the receiver connector of a second kind, hereinafter referred to as second socket.
  • This thrust or its reverse, the traction, carried out in the axis of the connector consisting of the assembly of the two sockets, is facilitated compared to the devices of the prior art.
  • the second part (18) is continued by a U-shaped part (19) which surrounds most of the first socket so as to shield it as efficiently as possible.
  • the second branch of the U (19) is completed by two parts (20, 21) which have two functions.
  • the side flaps 21a and 21b allow the first tap to be guided in an inlet channel for the second taken.
  • the comb (20) consisting of 8 curved tabs 201 to 208, makes electrical contact between the transfer part and at least one area of electrical ground either of the second socket or directly of the device on which cable is connected.
  • the teeth (20) are intended to form a pawl retaining the first grip on the second grip.
  • the comb formed by the teeth (20) disappears when the first plug is inserted into a housing containing the second plug and one edge of which comprises a member for retaining the ends of the teeth (20) of the comb.
  • this solution is adopted when it is not possible to secure the two sockets connected by external fixing members such as screws.
  • FIG 3 there is shown an exploded diagram of a preferred embodiment of a connector according to the invention.
  • the flat cable (30) is inside a protective sheath.
  • the first socket (38) is a HE10 type connector with two rows of holes (39) intended to receive the corresponding connection tabs of the second socket.
  • This second receptacle is soldered to the printed circuit on the back of an electrical device such as a computer peripheral.
  • the second socket (12) is mounted as shown in Figure 1 to inside the housing (13) of the device and set back relative to the access opening (130).
  • the sockets used (38, 12) are of the type known by the term "insulating removal socket".
  • the insulators surrounding the conducting wires of the sheet (37) are cut and moved by members electrically linked to the contacts accessible by the holes (39) of the first socket. These members allow by drilling the insulator to make a suitable electrical contact between the conductor and the pin of the first socket which is assigned to it.
  • the transfer piece (34, 35) according to the invention is inserted between the loop formed by the sheet (37) and a fixing piece (36) which comes to block the sheet on the socket (38).
  • a first end (350) of the transfer piece (34, 35) is arranged as a new comb.
  • U-shaped curved teeth, which extend in a spring at the rear of the socket (38) being slightly offset downward relative thereto.
  • this plate (34) of the transfer part comprises cutouts (340, 341) in the form of notches, so as to facilitate mounting in the sheathed flat cable (30) and / or armored.
  • the end (34) of the transfer piece is of reduced width and widens towards its end adjacent to a portion (351) of the comb (35). This end (34) is contained in a plane parallel and offset with respect to the planes of the legs of the U of the part (35).
  • a piece (36) also substantially in the form of a U is mounted so that the central part of the U of the piece (36) comes to be placed between the legs of the comb (35) in a U shape.
  • the ends of the legs of the piece (36) comprise lugs (360, 361) which are clipped into corresponding housings provided in the side blanks (380) of the socket (38).
  • Two jaws (31) and (32) of a clamp tighten the end (34) on the cable and ensure both the mechanical cohesion and the electrical continuity of the shielding on the transfer part (34).
  • the jaws are fixed to each other by four screws provided for this purpose.
  • the clamp may include two screws passing through the cylindrical openings (40, 41). Each of these screws is intended to enter a corresponding thread linked to the chassis of the device to which one wishes to connect the cable.
  • the jaws (31) and (32) are of dimension and shape adapted relative to the transfer part (34, 35) so that the extraction of the part (36) out of the comb (35) during an effort connection is not possible.
  • the ply (37) and the socket (38) come to bear on the central part of the U of the teeth (35), while during the extraction of the socket (38), the part (36 ) abuts on the central part of the U of the comb teeth (35).
  • the transfer piece according to the invention is mechanically fixed to the flat cable by gluing.
  • an adhesive with a conductive characteristic is used. If the cable is unshielded, the adhesive acts on the mechanical contact between the bundle of conductors and the transfer part or between the cable sheath and the transfer part.
  • the transfer part is doubled on the other face of the ribbon of conductors constituting the flat cable.
  • the two lateral halves (43) on the one hand, and (42, 45) on the other hand, of the transfer piece are connected by a part (44) which must be folded during assembly of the connector on its cable.
  • the first half (42, 45) also comprises a so-called front part which carries a U constituted by a folding of the conductive sheet. The end of the U is formed by teeth (47) and two side flaps (46, 48).
  • the ends introduced into the flat cable are identified (49, 50) and comprise, in a preferred embodiment, cutouts which reduce their width so as to facilitate the insertion of the transfer part according to the invention.
  • the user To mount the connector, the user must first make the connections of the conducting wires to the first socket according to a known method corresponding to the technology of the socket. Then he folds the transfer piece which is delivered in the unfolded form shown in Figure 4A. It then releases the sheath and / or the shielding fabric surrounding the bundle of conductors and easily introduces the transfer piece between the two. Finally, it fixes the transfer piece to the first socket using the relative flexibility of the transfer piece, the folded transfer piece having the appearance shown in FIG. 4B.
  • the connected cable is thus shielded in a rapid and economical and yet effective manner, and allows blind connection through a panel by the rigidity provided by the transfer part. Many connections and disconnections can be made without damaging the flexible cable while ensuring the continuity of the contact shielding on a copper pad of the printed circuit.
  • the invention admits of numerous adaptations, in particular in the case of a transfer piece completely surrounding the first socket. It adapts in particular to cables not only flat, but of all shapes.
  • the second socket can itself be connected to a second cable and no longer, as described here, to an electrical appliance.
